IRVIN R. BLOSE, OF SHARON, PENNSYLVANIA, ASSIGNOR' OF ONE-HALF TO WILLIAM DIXON, OF MARTIN'S FERRY, OHIO.

ROLLING-MILL.

Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed July 30, 1913.- seiial No. 782,054.

Toall'whom it'may concern:

Be it known that I, IRVIN R. BLosn, a citizen of the United States, residing at Sharon, in the county; of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Rolling-Mills, of which the following is'a'specification.

This invention relates to'certain new and useful'improvements in roll polishers, and relates particularly to a polish'er 'for'metal rolls such as are used in tin mills, sheet mills, plate mills or the like, in which sheets, plates, bars or the like are rolled.

The invention has for its main object the provision of roll polishers which maybe employed for polishing rolls during their operation without in any manner interfering with their operation or the operator.

The further object of this invention, is the provision of means whereby the emery stone or otherpolishing substancewhile in normally constant contact with the rolls may readily be changed to any position where polishing for that momentis desirable.

A still further object, is the arrangement of the'suspension means for'the upper polisher in such a manner that upon the break ing of a roll, the device will not be injured.

Still further objects and purposes'of this invention will appear from the drawings, the specifications describing the same and the claims appended thereto, in which are more fully set forth the arrangement of parts, combination of elements and specific structural details comprised witlilnthe scope of the same.

In the drawings in which'is shown a preferred embodiment of my invention, Figure 1 is a front elevation of the holisi'ng with rolls therein and my invention applied thereto, (housi'ng being shown withirrelevantportions omitted). Fig, 2, is a see tional'side elevation taken on line XjXof' Fig. 1, andlooking from left'to right on Fig.1, (that portion ofthe apparatus at the right of the housing in Fig. 1, being shown in dotted lines) Fig. 3, is a perspective view showing a fragmentary section of one of the housings, the relation of the rolls thereto and the method of attachment of the retaining 'means for the upper polisher. Figs. 4 and 5 are fragmentary detailviews illustrating the bifurcated ends of one'of the crossrods and oneofthe cross rod supporting arms, respectively.

Referring nowto the several figures in which like reference characters designate like "parts, 1 represents the housing; 2 the base plate; 3 the upper roll; 4 the lower roll. The rolls are provided with ordinary wabb'l'er connections 5'.

6 indicates the usual foreplate, the sup porting means of which however,- are omitted in the drawing.

At the front inner portion of each housing, adjacent the point of contact of the rolls, I provide brackets 7; in the brackets are jourii'aled the short shafts 8, these shafts at their inner ends are provided with the up wardly curved arms 9, 9. These arms are positioned adjacent the inner faces of the housings 'so that they are out of the line of feed of material to the rolls and their upper ends are substantially above the plane of the forep late. In a similar mannery'I provide arms' 10, which extend downwardly from the inner ends of the shafts 8 so that their ends lie below the foreplate and line offeed ofmaterial to the rolls. The outer ends of the shafts-8 are provided with gears 11.' These gears mesh with gears 13, which have bearings in blocks 12 positioned in front' of the outer ends of the shafts 8. Rigidly secured to the sides ofthe gears 13 are the forwardly extending levers let from the outer'ends of which are suspended the weights 15- by means of helical springs which aiford resilient connections between the levers and the weights and absorb any sudden shocks and jars which may be imposed on the machine during the operation thereof.

The upper ends of the arms9, 9" are provided with slots 16, in which the rectangular slide bar 17 rests. The rod 17 is fastened at its left end tothe upper end of arm 9by means ofthe bolt 19, while it is dependent solely upon its position within the slot for its connection to the upperend of the arm 9.

Slidably mounted upon the bar 17 is the holder 18, which is adapted to receive the emery" or other abrasive block 18.

Integrallv extending from the inner and. lower ends of the arms 10 are horizontal extensions 10 10". I

A rod 20 is fixedly secured at one end to the forwardendof 10, While the other end of'said rod is bifurcated as at 20 so as to receive the forward end of the member 10",

' 20 in event of the side movement of either housing.

Secured to the rod 20 is the downwardly extending foot lever 21, which is preferably positioned to the left of the middle of the rod. I

On the inner forward side of each housing at the base, I secure bearing blocks 22,- journaled in the rear upper portion of these blocks is the bar 23. Rigidlyfixed on either end of this bar, adjacent the blocks, are the gears 24:, which mesh with gears 26 of cor responding size. upon trunnions 25, having bearings in; the blocks 22.

Extending outwardly from and having fixed connection with the trunnions 25 and gears 26 are the levers 27, from the outer ends of which are suitably suspended the weights 28 by means of helical springs. As apparent from the drawings, the rod 23 between its points of bearing in the blocks 22 is rectangular in cross section. Slidably mounted on this rod 23 is the vertically positioned arm 29, provided at its upper end with means for holding the emery orv other abrasive material. Attached to this holder at a point adjacent the slide is a continuous cable 30 which passesover four pulleys positioned as shown more clearly in Fig. 1, so that the top stretch of the cable is beneath the forward part of the foreplate and readily accessible to the roller. I

Extending downwardly from the right side of the bar 23 is a foot lever 32.

In operation, my invention operates as follows: The weights 15 acting through the gears 11 and 13, press the arms 9 9 and the polishing block carried thereby against the upper roll. In same manner, the weight 28 acting through the gears 24 and 26 press the polishing block against the lower roll. When the roller desires to change the position of either one of the polishing blocks, the left foot lever is pressed rearwardly in the case of the upper polishingblocks, and the right foot lever pressed rearwardly in the. case of the lower polishing block.

7 When the left lever is pressed, the rod 20 and extensions 10, 10", the gears 11 and the arms 9 9' move away from the roll and in opposition to the weights 15. While the rod 17 is thus held away from the roll, the roller may slide the polishing block holder 18 to any desired position on the bar 17, and upon releasing the foot lever 21, the pollshing of the desired place begins.- When the roller presses the right foot 'lever 32 toward the rear, the slide bar 23 and the arm 29 is swungaway from the roll in opposition to theweight 28. The roller may now grasp the cable 30 at its upper and forward part, which it will be observed is The latter are mounted just under the forward part of the foreplate and readily accessible to the operator, and by moving the portion grasped either to the right or left, slide the polishing block 29 a corresponding distance in the opposite direction. The release of the foot lever j 32 then allows the block to be thrown back against the lower roll.

I It must ofcourse be understood that 1nstead of employing the weights 15 and 28, I may use any other suitable counterbalancing devices, the effect of which may be increased or decreased'in any well known manner, and with like effect as in the pres? ent case when the size of theweights are changed. 7

It will be observed that in the present device, all elements are so located as to be entirely out-of the roadv of either the roller or catcher, and while they do not interfere with the rolling of the material, yet are so positioned as to be easily and instantaneously operable by the roller, the man charged with the operation of the mill, without loss of his time or thefefliciency of the mill. 7 f As is well known, roll breakage is more or less inevitable, and must be provided for in'rolling mill equipment; Upon the breaking of a roll, the housings tend to separate. To prevent destruction of the apparatus in event of the breaking of a roll, I have so secured the rightend of the slide 17 and bar 20 in'the arm 9 and 10 respectively, as to permit the endwise withdrawal of the former without any damage to'the apparatus. In thecase of the bar 23, if the housing spreads at this point, one end of the bar will merely be withdrawn from its bearing block 22. V
